The authors present 2 cases: 1 of a thirty-two-year-old woman and anot
her of a thirty-eight-year-old woman, both Hispanic and athletic, with
no identificable precipitating or coronary risk factors, such as prev
ious heart disease, hypertension, diabetes mellitus, cigarette smoking
, hyperlipoproteinemia, oral contraceptive use, coagulation disorders,
thyroid disease, collagen tissue disorder, or family history of prema
ture myocardial infarction, who both developed an acute posteroinferio
r wall myocardial infarction with normal coronary arteries, one during
pregnancy, from which normal twin girls were born, and another, durin
g the postpartum period. After reviewing the literature the authors co
nsider the present cases as unique due to the rare association of preg
nancy with intrapartum and postpartum acute myocardial infarction with
normal coronary arteries in athletic women.
